Thanks for the response. There's a little more to the story than what I shared, but your information was helpful. As for me, I'm a married filing jointly with multiple dependents. Needless to say, I declared him as not my dependent and told him that he is going to need to amend his return because I believe he is supposed to pay Self-Employment Taxes for Medicare and Social Security if you make more than $400 on your 1099-NEC. He did not fill out a Schedule C or a Schedule 1040 SE which I believe he needs to. He just put down his income and that he paid no taxes with the standard deduction for a single filer and showed no tax liability due to the IRS.
